IMPROVEMENT IN APPARATUS FOR BAKING-AND BINDING GRAINL I The Schedule referred to in these Letters P n and making part of the same To all whom it may concern.-

Be it known that I, THOMAS K. GRIFFITH, of Redstoue, in the county of Fayette and State of Pennsylvania, have invented a new and useful Improvement in Machines for Baking and Binding Grain; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

The nature of my invention consists in constructing a machine for raking and binding grain by the combination and arrangement of the parts hereinafter described.

To enable othels skilled in the art to make and use my invention, [will proceed to describe more fully its construction and operation.

In 'the accompanying drawing' which forms part of my specification--' Figure 1, sheet A, is a top view or plan of my improvemcnt in machines for rakin'g and binding grain.

Figure 2 is a top view of a shifting piece used in connection with other mechanism for imparting a reciprocatiug motion to the rake.

Figure 3 is an end elevation of the same.

Figure 4 is a side elevation of the same.

Figure 5 is a section of the rod or bar, to which is attached a pendant, against which is gathered the grain for binding. A

Figure 6 is a side elevation of a section of the gathering-platform and rake.

Figure 7, sheet B, represents the rakiug-and-binding machine when it is inverted.

Figure 8 is an end elevation of the machine.

Figure 9 is a side view of a pair of pinchers, used for the purpose of looping and cutting thecord used in binding.

Figure 10 is an edge view of the same.

In the accompanying drawing- A represents the frame of the machine, and may be constructed of wood or metal.

tached to the head-piece B; the outer of the rods 2 are bent back at an obtuse angle to the longitudinal plane of the rods 2, as shown at 9, and just back of these angle ends are arranged the rake-teeth 7, which are pivoted to the rodsi2, as shown in figs. 6 and 8.

The outerend of the gathering-platform A is supported by a casterwh eel; a;"', clearly shown in fig. 8.

The rods 2 of the rake more in the grooved bars of the gathering-platform A, and in guides S, which are attached to one side of the frame A, and on a line with the grooved bars of the gathering-platlbrm.

Three bars, marked, 3, are placed across the upper side of the frame A, directly over the line of travel of the bars 2 of the rake, and from the bars 3, projecting downward, are arms or pendants marked 4, the lower ends of which are notched out, so as'to straddle the bar-s2 of the rake.

. At one corner-,and at'tlie'back end of theframe-A',

is pivoted, in suit-ablehea-n'ings, a shaft, to, to the lower end of which is attached a sector, E, to which, at l" and l', are attached the cords G, which pass around in grooves in' the outer edge of the sector, and around the pulleys D, and are connected to the head-piece B of the rake.

On the shaft x are two shifting pieces, 10, provided with rollers R, the form and arrangement of which are shown in figs. 1,2, 3, and 4. These pieces 10 are arranged on the shafts: in diiferent positions with relation to each other, so that they will'cause the shaft :0 Y

to rotate one-fourth of a revolution, giving to it a reciprocating motion, by the projecting points a coming in contactwith the rollers R in the piece to on the upper end of the shaft 2:, and then, by coming in contact with the rollers of the piece 10, placed on the shaft 1: below thc'npper piece w, so that the distance from the lower side of one piece to the upper side ot the other piece shall be equal to the diameter of the wheel 15", which is pivoted to the bearing 20 of the shaft 2:.

' The wheel B" gears into a small wheel on the end of shaft 1. On the opposite end of this shaft is also secured a small wheel, t, which gears into the wheel y, which revolves on axle z, to which the driving-wheels G are permanently attached.

On the axle z is placed a coupling, 12, which is fitted to the hub of the wheel 3/, and is slipped into and out of gear with the wheel y by means of the rod 0, which is operated by, the lever a, clearly shown in fi S.

lhc wheel y gears into the teeth at on the under side of the wheel 3, which is pivoted to the under side of the front end piece of the frame A'..

On the upper sideof the wheel 3 are teeth 2:, which gear into the wheel is on the shaft 1, on the inner end of which is placed the winding-arm h.

The shaft l is provided with a ratchet-wheel, s", which, in connection with the pawl and spring z, is psed for holding the shaft Z and its winding-arm h in a fixed position, after being rotated through the medium of the wheel I; and-teeth m on the upper face of wheel 3. The shaft Z has its hearings in the upper side of the front end piece of the frame A, and is hollow, as shown at s in tig. S.

The frame or support at for the drum f is secured on the front end piece of the frame A, and is so constructed that it will yield to the action of the tensionnut g on the end of the rod 9, and thereby bind the support n'agaiust the ends of the drum 1, so as to prevent it from turning too rapidly while drawing off the binding-cord during the operation of, binding the grain.

As the skilful mechanic will readily understand, the construction and arrangement of the machine and its several parts, and the relation that the ditferent parts bear to each other, I will thereflire proceed to describe the operation.

Having the hereinbefore-described rakmgaml-binding machine attached to a reaping-machine, so that the gatheririg-platformA will be directly back of the cutting device ofthe reaping-machine, and having on the drum fa suitable supply of cord for binding, with the outer endof the cord passed through the hollow shattland' t-l: winding-arm h, the operator beingprovided with pinchers, such as shown in tigs. 9 and 10, in which 16 represents the handles, 15, the cutter, and let the nippers, the operator takes. his seat (indicated by dotted lines I) and takes hold of the cord, (indicated by the dotted lines 26.) leaping-machine will cause the wheels 0' and their axle z to revolve, and by shipping, through the medium ot' lever n and bar 0, the coupling 12 into gear with the hub ofthe wheel 1,it will be revolved, which will revolve wheels 3-and t, and the revolving of wheel t will revolve the shaft P, which will revolvethe wheel 11, which will revolve the wheel B", which will bring the projections u 'up against the rollers R in the piece in, which will rotate the shaft 90 one-fourth of a revolution, which will turn the sector E into the position represented in fig. 7, which movement of the sector will, through the medium of cords 0, force the rake back until its teeth 7 assumea vertical position with relation to the gathering-plattbrin A, as shown in ti". The teeth 7 of the rake are thrown into a vertical position by trigger 6 coming in contact with the piece 5 on the side of the gathering-plattbrm, (see tig. U.)

The wheel 15' continuing to revolve will carry the projecting pieces a down against rollers Itin the lower piece to, and thereby turn the shaft 00 back one-tburth ot'a revolution, which will throw the sector E into the position shown in fi 1, which will, through the mediumof the cords 0, cause the rake to gather the grain which has fallen on the platform A gp'into a bundle, and against the pendants hat this point the die of gathered grain.

Now, the forward motion of the teetlraijvill gear into wheel 70, andy ivethe shaftl about two revolutions, which will cause the winding- I arm h to wind the binding-cord twice around the bun- The operator then, with the pin'cher hereinhefore described, takes hold of the cord with the nippers 14 of the pinchers, and forces the end of the cord which he held in his hand in under the cord wrapped around the bundle, and before he withdraws the points of the nippers from under the cord, which is around the bundle of grain, he gives the pinchers a twist, so as to cause the cutter 15 to cut the cord leading from the winding-arm h to-the bundle, the operator having hold of that portion-of the cord next to the winding-arm h. I

The rake, in moving back, for the purpose of gathering another bundle, will allow the bound bundle to drop down from the machine. Thus will the several parts as described continue to operate, gathering and binding one bundle after another, while the reapingmachine is in operation.

The angle form of the ends Dot the bars 20f the rake isfor the purposeof allowing the bars to pass readily under the grain during the back motion of the rake, and the teeth 7 are pivoted, so that they will assume a horizontal position during the same motion of the rake. The inclined rods are used for throwing the grain forward on the gathering-platform, and to give room. for the teeth of the rake to assume a vertical position.

The guide D'is use'l for the purpose of shaping and squaring the end of the bundle of grain during the forward movement of the rake and grain toward the pendants 4.

The piece y is for preventing the bundle from being carried back onto the gathering-platfin'm.

Having thus described the nature, construct-ion, and operation. of my improvements,

Vhat I claim is- '1. The gat-hering-platfintni A, combined with the rake, bperated thrugh the medium of cords O, pulleys D, and a segment, E, having a reciprocating motion, said motion being imparted to the segment by means of shafts and gearing, the whole being constructed, arranged, and operating substantially in the manner herein described and for the purpose set forth.

2. The binding device, consisting of drum f, ten.- sion-shaft g, winding-arm h, operatedtln'ough the medium of pinion k on shaft 1, and wheel 3, constructed, arrz'mged, and operating substantially as herein described and for the purpose set forth.
